2015 LINCOLN NAVIGATOR maintenance reset

If you drive in extremely hot climates:
•It may be necessary to have a Ford authorized dealer decrease the
coolant concentration to 40%.
• A coolant concentration of 40% will provide improved overheat
protection. Engine coolant concentrations below 40% will decrease the
corrosion/freeze protection characteristics of the engine coolant and
may cause engine damage.
Vehicles driven year-round in non-extreme climates should use
prediluted engine coolant for optimum cooling system and engine
protection.
What You Should Know About Fail-Safe Cooling
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The fail-safe distance depends on ambient temperatures, vehicle load and
terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the engine coolant temperature gauge
will move to the red (hot) area and: The coolant temperature warning light will illuminate.
The service engine soon indicator will illuminate.
If the engine reaches a preset over-temperature condition, the engine
will automatically switch to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.
When this occurs the vehicle will still operate. However:
• The engine power will be limited.
• The air conditioning system will be disabled.
Continued operation will increase the engine temperature and the engine
will completely shut down, causing steering and braking effort to
increase.
Once the engine temperature cools, the engine can be restarted. Take
your vehicle to an authorized dealer as soon as possible to minimize
engine damage.

If you see any corrosion on the battery or terminals, remove the cables
from the terminals and clean with a wire brush. You can neutralize the
acid with a solution of baking soda and water.
It is recommended that the negative battery cable terminal be
disconnected from the battery if you plan to store your vehicle for an
extended period of time. This will minimize the discharge of your battery
during storage.
Because your vehicle’s engine is electronically controlled by a computer,
some control conditions are maintained by power from the battery. When
the battery is disconnected or a new battery is installed, the engine must
relearn its idle and fuel trim strategy for optimum driveability and
performance. To begin this process:
1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift in P (Park), turn off all accessories and start the
engine.
3. Run the engine until it reaches normal operating temperature.
4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for at least one minute.
6. Drive the vehicle to complete the relearning process.
•The vehicle may need to be driven 10 miles (16 km) or more to
relearn the idle and fuel trim strategy.
• Note: If you do not allow the engine to relearn its idle trim, the idle
quality of your vehicle may be adversely affected until the idle trim is
eventually relearned.
If the battery has been disconnected or a new battery has been installed,
the clock and radio settings must be reset once the battery is
reconnected.
CHECKING THE WIPER BLADES Run the tip of your fingers over the edge of the blade
to check for roughness.
Clean the wiper blades with washer fluid or water
applied with a soft sponge or cloth.

Protecting Your Investment
Maintenance is an investment that will pay dividends in the form of
improved reliability, durability and resale value. To maintain the proper
performance of your vehicle and its emission control systems, it is
imperative that scheduled maintenance be completed at the designated
intervals.
Your vehicle is equipped with the Intelligent Oil-Life Monitor (IOLM)
system which displays a message in the information display at the proper
oil change service interval; this interval may be up to one year or
10000 miles (16000 kilometers). When ENGINE OIL CHANGE DUE or
OIL CHANGE REQUIRED appears in the information display, it is time
for an oil change; the oil change must be done within two weeks or
500 miles (800 kilometers) of the ENGINE OIL CHANGE DUE or OIL
CHANGE REQUIRED message appearing. The Intelligent Oil-Life Monitor
must be reset after each oil change; see theInformation Displays
chapter.
If your information display is prematurely reset or becomes inoperative,
you should perform the oil change interval at six months or 5000 miles
(8000 kilometers) from your last oil change. Never exceed one year or
10000 miles (16000 kilometers) between oil change intervals.
Your vehicle is very sophisticated and built with multiple, complex,
performance systems. Every manufacturer develops these systems using
different specifications and performance features. That is why it is
important to rely upon your dealership to properly diagnose and repair
your vehicle.
Ford Motor Company has recommended maintenance intervals for
various parts and component systems based upon engineering testing.
Ford Motor Company relies upon this testing to determine the most
appropriate mileage for replacement of oils and fluids to protect your
vehicle at the lowest overall cost to you and recommends against
maintenance schedules that deviate from the scheduled maintenance
information.
Ford strongly recommends the use of only genuine Ford, Motorcraft or
Ford-authorized remanufactured replacement parts because they are
engineered for your vehicle.
Additives and Chemicals
Ford Motor Company recommended additives and chemicals are listed in
the owner manual and in the Ford Workshop Manual. Additional
chemicals or additives not approved by Ford Motor Company are not
recommended as part of normal maintenance. Please consult your
warranty information.
